Printer&#39;s quoin.



ORIE E. VESSELS, OF INDIANAPOLIS, INDIANA.

PRINTERS QUOIN.

Specification of Letters Patent.

Patented Feb. 2, 1909.

Application filed April 25, 1907. Serial No. 370,279.

To all whom it may concern:

Be it known that I, ORIE E. VESSELS, a citizen of the United States, residing at Indiana olis, in the county of Marion and State of In iana, have invented certain new and useful Improvements in Printers Quoins, of which the following is a specification.

This invention relates to improvements in printers quoins, and the object is, first, to provide a positive means for looking together the two wed es of which the device is comprised so as to keep them from accidentally sliding and becoming loosened, and second, to provide means in the construction of the quoin, to hold the type form on its feet and thereby take the spring out of the form.

I accomplish the objects of the invention by the mechanism illustrated in the accompan ing drawing, in which Figure 1 is a detail in top lan view of a printer's chase and a piece of urniture, with my improved quoin in operative position. Fig. 2 is a vertical section on the line 22 of Fig. 1. Fig. 3 is a top plan view of my invention in the same position as shown in Fig. 1, with parts broken away to illustrate the un derlylng formation, and Fig. 4 is a view of the inner oblique face of one of the wed es.

Like characters of reference indicate Tike parts throughout the several views of the drawing.

5 is a ortion of a rinters chase and 6 a piece of urniture such as is commonly used to bear against the type matter (not shown) of the form and my improved quoin is shown between the furniture and chase. The latter comprises a air of similar wedges 7 and 8 each having the lugs 9 at their thickened ends on their adjacent faces. These adjacent faces are the oblique ones of the wedges and are provided with a longitudinal central flange 10 extending from the lug 9 to the opposite end of the wed e, and each of the lugs 9 is provided with a longitudinal slot 11 to receive the flange 10 of the opposite wedge. The inner oblique faces of each wedge on both sides of theflange 10 are provided with the teeth 13 to engage with the toothed end of a wrench, which is used in the usual way for tightenin up the form by sliding the Wed e shaped sections of the quoin longitudina 1y upon each other.

As thus far described the construction is the same as quoins heretofore in use, and the operation of such a device has not always been satisfactory for the reason that the wedges will slide back and loosen under strain. I obviate the possibility of this loosening by forming a tooth or lug 16 at the inner end of the slot 11, and provide a series of indentations or notches 18 along the major ortion of the flange 10 the notches 18 formmg the teeth 17. The tooth 16 of each wedge by entering a notch 18 in the flange of the opposite wedge provides a positive lock which will prevent the accidental movement or slipping of the two wedges u on each other. The lugs 9 are lon enougii to hold the quoin members out 0 en agement at their portions 10, as shown in igs. 1 and 3 and said lugs 9 are also longer than the teeth 16.

Another feature of my invention consists in adding an extension 20 to the outer face of each wedged section of the quoin at diagonally opposite appearing edges when the two wedges of the quoin are assembled. The quoin will be turned when placin it in the form so that the shoulder formed y the extension 20, 011 that face which is adjacent to the furniture 6, will be lowermost. The thickened portion of the opposite wedge will be up, as clearly shown in Fig. 2. This thickening of the quoin at the parts named has a tendency to tilt the quoin in a direction to force down the type form, so as to keep the latter on its feet and take the spring out of the type form.

Havin thus fully described my invention what I c aim as new and wish to secure by Letters Patent of the United States, is-

1. A printers quoin comprising a pair of wedges with oblique adjacent faces, the thick end of each wedge having a lug to bear against the other wedge, a ongitudinal centrally located flange extending from each lug to the thin end of its wedge, said flange having a series of indents to form a series of teeth, there being a tooth on each side of each indentation, said lugs on the thick ends of the wedges being grooved to receive the flange of the opposite wedge and said lugs each having an integral tooth no longer than its lug at the inner end of its groove to engage a corre sponding one of the indents of the ion itudinal flange to keep the wedges from slit. in in either longitudinal direction on each ot ier from the vlbration of the press said lugs being long enough to hold the flanges out of contact with each other.
